Reinterpreting the results of the LHC with MadAnalysis 5: uncertainties and higher-luminosity estimates

Abstract : The MadAnalysis 5 framework can be used to assess the potential of various LHC analyses for unraveling any specific new physics signal. We present an extension of the LHC reinterpretation capabilities of the programme following for the inclusion of theoretical and systematical uncertainties on the signal in the reinterpretation procedure. We have implemented extra methods dedicated to the extrapolation of the impact of a given analysis to higher luminosities, including various options for the treatment of the errors. As an application, we consider a simplified new physics model in which the Standard Model is supplemented by a gluino and a neutralino and investigate the effect of the errors on current bounds and the corresponding high-luminosity LHC expectation. We show that uncertainties could, in particular, degrade the bounds by several hundreds of GeV when considering 3000 fb-1 of future LHC data.
